Question

What is the sign of product, if we multiply 90 negative integers with 9 positive integers

Answer 1

For this, let's take an example. If we multiply 2 negative integers we get a positive integer but if we multiply 3 negative integers we get a negative integer.

So, notice that I multiplied with an even number to get a positive integer while I multiplied with a odd number to get a negative integer.

Taking the same sense here. We can conclude that 90 is an even number so the integer I'll be positive so, let's denote it with the value

-A * -A..... 90times = +A

Secondly 9 is a odd number but the integers are positive so, no matter what, the internet obtained will also be positive. So,

A * A...... 9times = +A

Now we multiply the products with each other obtained in both the equations.

+A * +A = +A

Therefore, +A is your answer which means the integer by multiplying negative integers 90 times with positive integers 9 times, we get a positive integer.
